OIL BURNER.

Application filed May. 17,

This invention relates to oil burners'of the gravity feed type, and hasfor its object the production of a bin-ner which is simple andinexpensive of construction, efiicient in oper ation and of universalapplication to any of the sta 'dard and. usual types of furnaces.

A further object includes the production of a burner of the typespecified which is designed and constructed to be madein sections orparts for ready and easy installation in the usualtype of grate furnace.

Another object includes the production of a burner construction which issurface burning and wherein the oil is vaporized by the agency of avaporizing device which is constructed of a metal of greaterconductivity than that from which the body of the burner device isconstructed. 7 j

Other objects willappear hereinafter, and I attain these results by theconstruction illustrated in the accompanying drawing in which Fig. 1 isa plan view of a furnace supplied with a burner device embodying theprinciples of my invention.

Fig. 2 is a section taken on the line 22 of Fig. 1.

Fig. 8 is a sectional view of the burner taken on the line 33 of Fig. 4,and

Fig. 4 is a View taken on the line -,4 of Fig. 3 looking in thedirection of the arrows.

Like numerals refer to similar parts throughout the several views.

. It is among the prime objects of my invention to produce a universalburner of such simple and inexpensive construction as to be within.reach of the average householder, and which may be readily applied bythe average mechanic to the usual heating plant without alterationsthereof. To this end I provide a burner base or thimble 10 having a seator foot end 11 and an oil distributing and burner part or infold 10. Thefoot end rests on a suitable baseor supportl2 which may be a plate or anannular ring made in two sections for convenience in handling andinstallation. The oil distributing and combustion part 10 is cast or isotherwise formed integral with the thimble 10 and comprises a slopingsurface having oil distributing rings or corrugations 13 on the upperside, a pipe retaining rib 14 on the lower side,an oil basin 15 and acentral air inlet and hood support 16 on which is seated the hood ordeflector 17 Oil feed openings 18 are -pro vided in the sloping surface10 and through 1924.

the retaining rib 1%. Into these openingsare ecu ed the oil feed pipes19 and immediately adjacent the corrugations-I provide the va-..;ing]r"ember 20 in the shape of aring'of conductivity, such as copperor brass high 101' e: by lugs 21 in the immediate path of theinflowing'air entering through the air inlet ports 22 of the hoodsupport 16 in the de fiector 1'7. Immediately over these ports I providethe deflector canopy 23 which has a central depression Q-tand curvesoutwardly to direct the iii-sowing draft onto the open flan-1e of inndescent gas to be thence diected outffardly by the flaring skirt 25 ofthe deflector 17.

it my improved burner is installed in a coal-burning furnace, the twosections of base pistes or rings 12 are placed directly on .e furnacegrate bars 26, and the oil feed me 19 mayextend between the grate bars 0be connected by branches 27 to the usual oil feed valve 28 and pipeconnection 29. The oil feed valve is connected to a drip vessel 30 whichcollects the overflow oil from the burner by means of pan 31 and pipe32.

Obviously the oil feed Valve 28 may be further controlled by athermostat to thus automa ically regulate the oil feed. To in- 8 creasethe draft through the ports 22 for the more effective use of my device,I cover the unoccupied portion of the grate bars with asbestos cement 35or the like.

From the above disclosure thus far given, the operation of my devicewill be readily understood. To start the burner, the vaporizing ring isheated. This may be ac complished by permitting a quantity of oil tocollect in the well 15 and igniting the same until the vaporizing ringperforms its function to vaporize the oil as it creeps or flows over thecorrugations. The inrushing draft through the openings 22 will supplythe oxygen needed for complete combustion, and the degree of heat isregulated by the rate of oil feed and its combustion.

ample. This ringmay be held seated As a means of safety and to cut offthe I flow of the oil after the flame has been eX- vention, and desireto secure by Letters Patent is 1.. In an oil burner, a burner thimblehaving an infold with a central opening, said infold sloping towardssaid opening and being provided with a plurality of oil feeds, oildistributing members adjacent said feeds and a vaporizing memberadjacent said distributing members, a deflector member seated on saidinfold, said deflector having openings to direct the air currents on tothe vaporizer and over the oil distributors.

2. In an oil burner, a burner thimble hav ing an infold with a centralopening, said infold sloping towards said opening and being providedwith a plurality of oil feeds, oil distributing inen'ibers adjacent saidfeeds and a vaporizing member adjacent said distributing members, adeflector member seated on said infold, said deflector having openingsto direct the air currents on to the vaporizer and over the oildistributors, said infold having a pocket to form an oil Well forstarting the burner.

8. An oil burner comprising a thimble having an infold terminating in anup turned neck, a seating base plate for said thimble, a deflectormember seated on said upturned neck, said infold being provided With oildistributing means and oil vaporizing means, said deflector havingopenings for causing air currents to flow over said infold, and aremovable combustion ring on said infold for vaporizing the inflowingoil.

In an oil burner, the combination of a furnace and a burner base,includinga thimble portion and an infold burner part, said burner partbeing provided with oil inlets near the outer periphery, a vaporizernear its inner periphery, said vaporizer having a higher temperatureconductivity than said burner Jart and means for cans 7 ing air to befed on to said vaporizer and towards the oil inlets.

In testimony whereof I have hereunto set my hand on this 16th day of MayA. D., 1924.
